Anti-theft device for mobile telephone, has control unit that determines property of armature coupled between stationary object and electronic device based on electric signal received at armature, and outputs alarm control signal
Anti-theft device for mobile telephone, has control unit that determines property of armature coupled between stationary object and electronic device based on electric signal received at armature, and outputs alarm control signal
The device has a cable connection armature (2) coupled to a stationary object (3), secured mechanically to an electronic device (1). A plug (9) electrically connects the armature and a control unit (4). The control unit determines the property such as inductance, impedance, admittance and/or resistance value of transmission link of the armature based on the electric signal (13) received at the armature, and outputs alarm control signal according to the determined result in order to activate the security function. An independent claim is included for method for safeguarding electronic device against theft.
